Cardinal Crabapple

Malus 'Cardinal'

The Story

Plant Bio

Flowering crabapples are small to medium-sized deciduous trees, highly valued for their spectacular spring floral displays, colorful fruit, and often attractive foliage and form.

'Cardinal' is a standout cultivar noted for its vibrant, purplish-red single flowers that smother the branches in spring. It also features reddish-purple foliage that matures to bronze-green and persistent, glossy, dark red fruit.

Uses & Benefits:

'Cardinal' is a premier small ornamental tree, offering a multi-season display. It explodes with vibrant red flowers in spring, followed by attractive purple-tinged summer foliage. In fall and winter, the persistent glossy red fruits add color and attract wildlife.

Its compact, spreading habit makes it an excellent choice for urban and suburban landscapes, fitting well into smaller yards, near patios, or along driveways. It is also tolerant of clay soils, which are common in many residential areas.

The flowers are an important early-season pollen and nectar source for bees and other pollinators. The small, persistent fruits are a crucial food source for overwintering birds, such as cedar waxwings, robins, and finches.

Planting

How to Grow

Select a site that receives at least 6 hours of direct sun daily.
Dig a hole twice as wide as the root ball and just as deep.
Place the tree in the hole, ensuring the graft union is above the soil line.
Backfill with the original soil, breaking up any large clumps.
Water deeply to settle the soil around the roots.
Mulch around the base, but do not let it touch the trunk.

Pro Tip

Ensure full sun exposure and good air circulation to maximize flowering and minimize the risk of fungal diseases like apple scab.

Keep It Thriving

Care Guide

Do

Provide consistent water for the first few years.
Prune out any suckers that emerge from the base or roots.
Rake up and dispose of fallen leaves in autumn to reduce disease.
Choose disease-resistant cultivars like 'Cardinal'.
Allow ample space for the tree to reach its mature size.

Don't

Do not plant in a shady or poorly drained location.
Avoid heavy nitrogen fertilization, which promotes leafy growth over flowers.
Don't over-prune; remove only what is necessary for health and structure.
Avoid overhead watering, which can encourage fungal diseases.
Do not plant other susceptible apple or crabapple trees nearby if disease is a concern.
